IMPROVEMENT IN TELEGRAPH SOUNDERS AND RECORDERS.

specifio'ation forming part of Letters Patent No. 160,271, dated March2, 1875; application filed July 17, 1874.

To all whom it may concern:

Be it known that I, DANIEL F. LEAHY, of Portland, Oregon, have inventedcertain new and useful Improvements in Telegraph Instruments, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings making a part of this specification, inwhich- Figure l is a front elevation; Fig. 2 is a plan view. I

My improvement relates to telegraph instruments used for thetransmission of messages and it consists in the combination of deviceshereinafter described and explained.

To enable others skilled in the art to make and use my invention, I willproceed to describe the exact manner in which I have carried it out.

In the drawings, A A represent spools attached to shafts in reels B B.On thesereels the ribbons of paper are coiled in such manner that whenthe weight 0 attached to the spool A is started, the paper is woundoifone reel and onto the other. The paper in the mean time passes over aconcave metal plate, H, and under the rollers J and O. The concavesurface of the plate H allows the paper D to spring slightly away from,the pen E on the descent of the sounding-bar attached to the magnets.The plate H may be made flat, but a better effect is produced by theconcave form. The pen E is a common right-line pen, adjusted verticallyby the screws L F on the horizontal slide G, which is made to slidefreely in or out of the end of the sounding-bar N. It is also graduate-dso as to regulate the distance between the lines of letters made by thepen, thus enabling me to use the same paper until its surface becomesfilled. P is a feeder filled with ink, which passes through a smalltrough, Q, to the pen, keeping the pen always supplied. S is a brake toarrest the movement of the paper.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The adjustable pen E, provided with the inking attachment P and thesupplying-trough Q, in combination with sounder N, substantially as andfor the purpose set forth.

2. In combination with the sounder N and pen E, the concave plate H,substantially as and for the purpose set forth.
